:whs You have a 50/100 mile window approx post cam break-in to load up & scuff those rings in IMO after this things are a lot slower happening Thanks. Sorting out the clutch, last brake to pipe fit etc (and what I've got stored in the back of it) so I can get some street time on it. Appreciate the ...

Have you run it at 2000 rpm for a while to help bed in the rings? Ian Had a bit of time today so ran it up for about 15/20 mins first time and smoke built then started to fade to almost non existent on one side. Running with electric fans so gave it a break to cool once heater needle started to mov...

Have you run it at 2000 rpm for a while to help bed in the rings? Ian Hi Ian I've stopped each time (about 5 or 6 now) after about a minute as smoke just seems to be getting thicker and didn't want to be damaging anything/blowing seals etc. This time possibly slower to start smoking and maybe not s...

The Thor engine (final incarnation in P38 Range Rover / Disco II) runs at about 60PSI. If you completely remove the crankcase ventilation system (so it just breaths to atmosphere), and plug any holes into the carb / inlet manifold, does it still do it? Chris. Thanks Chris I'll give it try next oppo...

Bit of an update if anyone has some further thoughts.. Fitted verified quality rockers, and also drained oil and measured it back in so I now know I have the right quantity oil and good rockers. Fitted a smiths oil pressure gauge and fired it up.. (Spun it on the starter with booster battery and dis...

Hi Dave, certainly wiggling the old rockers off their shaft was a snug fit but I put the ease of fitting on new ones on new shaft to lack of crud build up. I should have been a bit more critical perhaps. I could get some sideways wiggle on the new rockers in situ (the ones not under load) with my fi...

Thanks for breather thoughts. The one I built ages back I routed the two flame trap (small grey) pipes to the underside of the aircleaner which seemed to work fine. Ran it on LPG/petrol and seemed to work ok for both. This one I started out with two small k&N style filters on (P6 style) rocker cover...

Thanks for thoughts Sidecar and Ian Anderson (a local perhaps). I fitted new well lubed valve guides and cranked engine minus plugs to get oil pressure up a couple of times before first start up so hoping valve stem seals are good. I ran it briefly with flame trap (large type) routed to center manif...

Hi Dave Thanks for reply Yes did some de-glazing, looked about right. I'm currently on the loose rocker trail as I fitted what I thought would be better aftermarket alloy ones, but after reading some posts and wiggling them they are a pretty loose fit. Running with a rocker cover off there was oil s...

Hello All I've a newly built rover V8 SD1 engine start up question. It's taken me a couple of years of spare time here and there but re built engine is in and running. Starts and runs nicely, sounds good (second one I've built, other about 20 years ago). After about 30 seconds to a minute it starts ...
